Access Boating mode on my nüvi® 500 series device
In order to access the Boating usage mode on a nüvi® 500 series device, a compatible marine map must first be installed either directly to the device or on an inserted microSD card.
Once the nüvi® has access to marine maps, the usage mode can be changed to Boating by touching the usage mode icon in the top-center of the main menu. Boating should be displayed as an available usage mode.
Compatible marine maps and bluecharts for the nüvi® 500 series are available on the Garmin website.
